Explanation:

(a) The distance travelled by the object is  100 m.

(b) The displacement of the object in time interval between t = 0 s and t = 10 s is 60 m.

(a) The distance travelled by the object is calculated from the total area of the curve.

total distance = area of triangle 1 + area of triangle 2 + area of rectangle.

total distance = (¹/₂ x base x height)₁ +  (¹/₂ x base x height)₂ + length x width

total distance = (¹/₂ x 6 s x 20 m/s) +  (¹/₂ (8 - 6) 20) + (10 - 0)(10 - 8)

total distance =  60 m + 20 m + 20 m

total distance = 100 m

(b) The displacement of the object in time interval between t = 0 s and t = 10 s is calculated as follows;

displacement = final position - initial position

displacement =  (¹/₂ x base x height)₁ +  (¹/₂ x base x height)₂ + length x width

displacement = (¹/₂ x 6 s x 20 m/s) +  (¹/₂ (8 - 6) (-20)) + (10 - 0)(10 - 8)

displacement = 60 m - 20 m + 20 m = 60 m

The 950 W has higher resistance in the given situation.

The current flow is inversely correlated with resistance. If abnormally high, damaged conductors from osicorron or burning could be one of a number of potential causes. Overheating is a problem that is frequently connected to resistance because all conductors emit some amount of heat.

When all linked devices, whether in parallel or series, are considered, the equivalent resistance is the value at which the total resistance between them is calculated. A circuit is fundamentally constructed as either a parallel or series circuit. Electrical resistance, which is the amount of energy required to carry charges or current through your devices, is visible.

The shear deformation of the disk under the given conditions is approximately 0.00589 meters. To find the shear deformation of the disk, we can use the formula Shear Deformation = (Shear Force * Disk Height) / (Shear Modulus * Disk Area)

Shear Force = 540 N

Shear Modulus = 1.00×10^9 N/m^2

Disk Height = 0.700 cm = 0.007 m

Disk Diameter = 4.20 cm = 0.042 m

First, we need to calculate the area of the disk. Since the disk is equivalent to a solid cylinder, its area can be calculated using the formula:

Disk Area = π * (Disk Diameter/2)^2

Disk Area = π * (0.042 m/2)^2

Next, we can substitute the values into the shear deformation formula:

Shear Deformation = (540 N * 0.007 m) / (1.00×10^9 N/m^2 * π * (0.042 m/2)^2)

Shear Deformation ≈ 0.00589 m

The phase difference for 486.1-nm light in the double-slit interference pattern is equivalent to a path difference resulting in an intensity of 64.0% of the maximum value.

In a double-slit interference pattern, light waves pass through two slits and interfere with each other, creating regions of constructive and destructive interference. The intensity of the pattern depends on the phase difference between the waves reaching a certain point on the screen. When the waves are in phase (peak to peak and trough to trough), constructive interference occurs, resulting in a maximum intensity. When the waves are out of phase (peak to trough), destructive interference occurs, leading to a minimum intensity.

The given information states that the intensity at a certain point on the screen is 64.0% of the maximum value. This implies that there is a phase difference between the two interfering waves at that point. By determining the phase difference, we can express it as a path difference for the specific wavelength of light.

To find the phase difference, we can use the fact that at a certain point in the interference pattern, the path difference between the two waves should be equal to half of the wavelength for destructive interference. Since the intensity is not zero but 64.0% of the maximum, it indicates that the waves are slightly out of phase.

The phase difference can be calculated by considering the fraction of the wavelength by which the waves are out of phase. As the intensity is 64.0% of the maximum, it corresponds to a path difference equal to one-fourth of the wavelength.

Mechanical energy (kinetic or potential energy) is the energy of an object in motion or the energy stored by an object in its position. Mechanical energy is also the engine of renewable energies.

Now,

the total mechanical energy is:

   E(i) = U = mgh

⇒ E(i) = 55×9.81×8

Kinetic energy is the energy that an object possesses due to its motion. If we want to accelerate an object, we must apply a force. The application of force forces us to work. After the work has been done, the energy has been transferred to the object and the object will move at a new constant speed.

And, the kinetic energy :

   E(f) = K = (1/2) mv²

⇒ E(f) = 0.50 × 50 × 12

⇒ E(f) = 3600 J

So, the energy lost by the Justin:

   ΔE = E(i) -E(j)

Explanation:

The temperature T of the lump of metal after t minutes, assuming it obeys Newton's Law of Cooling, can be expressed as T = -30kt + 30. However, the value of the cooling constant k is not provided, so it is not possible to determine the exact temperature without additional information.

Newton's Law of Cooling states that the rate of change of temperature of an object is directly proportional to the temperature difference between the object and its surroundings. Mathematically, this can be expressed as:

dT/dt = -k(T - Ts)

where dT/dt is the rate of change of temperature with respect to time, T is the temperature of the object, Ts is the temperature of the surroundings, and k is the cooling constant.

In this case, we can use the given data to find the value of k. After 10 minutes, the temperature of the lead block was 60oF, and the temperature of the surroundings was held constant at 80oF. Plugging these values into the equation, we have:

dT/dt = -k(60 - 80)

Simplifying the equation, we get:

-30k = dT/dt

Integrating both sides, we have:

∫-30k dt = ∫ dT

-30kt + C1 = T

Since the initial temperature of the lead block was 30oF, we can substitute t = 0 and T = 30 into the equation:

-30k(0) + C1 = 30

C1 = 30

Therefore, the equation for the temperature of the lump after t minutes is:

T = -30kt + 30

To determine the temperature T after a specific time t, we need to know the value of k.

During the process all IMFs break and the solvent vaporizes.

During the boiling process, the solvent (hexanes) reaches its boiling point (68.73 °C) and vaporizes, meaning it changes from a liquid to a gas. The boiling point of a liquid is the temperature at which its vapor pressure is equal to the atmospheric pressure. The solvent molecules need to gain enough energy to overcome the intermolecular forces (IMFs) between them to change phase from liquid to gas. The process of vaporization requires an input of energy, which is supplied by heat. The heat energy provided causes the solvent molecules to absorb enough energy to overcome the IMFs, and the solvent vaporizes.

IMFs are the forces that hold the molecules of a substance together, and these forces are weaker in gases than in liquids. When the solvent vaporizes, the IMFs between the solvent molecules are broken, and the solvent molecules move freely in the gaseous state. So, in this case, during the boiling process, all IMFs break and the solvent vaporizes.

To find the direction of the vector c = 2a - b, we first need to calculate the components of the new vector c.
1. Multiply vector a by 2:
2a = 2(12i - 16j) = 24i - 32j
2. Subtract vector b from the result of step 1:
c = 2a - b = (24i - 32j) - (-24i + 10j) = 24i - 32j + 24i - 10j
